SSL certificates some times maybe pain on the xxx.​


i used webmin and usermin with Almalinux with Let's Encrypt

Test Tools i use
CERT FAIL
Certificate #1 of 2 (sent by MX):
Cert VALIDATION ERROR(S): self signed certificate
So email is encrypted but the recipient domain is not verified


result T or F

what is a good valid way to issue an SSL certificate for smtp and web ?

i try it .. probably i m doing something wrong just because i have similar results with the above
the results show that Cloudflare is installed correct with the panel (for web and smtp)

example of errors
checktls.com
Code:
Certificate #1 of 1 (sent by MX):
Cert VALIDATION ERROR(S): unable to get local issuer certificate; unsupported certificate purpose
This may help: What Is An Intermediate Certificate
So email is encrypted but the recipient domain is not verified
Cert Hostname DOES NOT VERIFY (mail.domain.com != Cloudflare)
So email is encrypted but the host is not verified

Code:
https://www.ssllabs.com/

another T
with Cloudflare this time

When using cloudflare, when Let's Encrypt expires it cannot be updated automatically, return to the original registrar ns then renew the SSL on the hosting and change back to cloudflare ns and it will work again.
Or should we use cloudflare SSL if we also use a CDN on cloudflare, I haven't tried this.
